Abstract

A fixture and method for adjusting a workpiece are disclosed. The fixture includes a holding device engageable to a workpiece to secure the workpiece, and an adjustment device engageable to a projecting member of the workpiece and movable along a first axis and a second axis. Movement of the adjustment device along the first axis when engaged to the projecting member adjusts the projecting member along the first axis, and movement of the adjustment device along the second axis when engaged to the projecting member adjusts the projecting member along the second axis.

First claim

What is claimed is:

1. A fixture for adjusting a transition piece, the fixture comprising:
a holding device engageable to the transition piece to secure the transition piece; and
an adjustment device engageable in contact with a mounting bracket connected to and projecting from a body of the transition piece and movable along a first axis and a second axis,
wherein movement of the adjustment device along the first axis when engaged to the mounting bracket adjusts the mounting bracket along the first axis relative to an aft frame of the transition piece, and wherein movement of the adjustment device along the second axis when engaged to the mounting bracket adjusts the mounting bracket along the second axis relative to the aft frame.

2. The fixture of claim 1 , wherein the adjustment device comprises a movable member and an engageable member.

3. The fixture of claim 2 , wherein the movable member is a hydraulic cylinder.

4. The fixture of claim 2 , wherein the engageable member comprises a bracket and a pin, the pin extendable through the mounting bracket and the bracket to engage the mounting bracket.

5. The fixture of claim 1 , wherein the adjustment device is pivotable between a first position wherein the adjustment device is movable along the first axis and a second position wherein the adjustment device is movable along the second axis.

6. The fixture of claim 1 , further comprising a locating device configured to assess a location of the mounting bracket.

7. The fixture of claim 1 , wherein the holding device is a clamp.

8. The fixture of claim 1 , wherein the holding device is engageable to the aft frame of the transition piece.

9. The fixture of claim 1 , wherein the first axis is an x-axis and the second axis is a z-axis.

10. A fixture for adjusting a workpiece, the fixture comprising:
a holding device engageable to a workpiece to secure the workpiece; and
an adjustment device engageable to a projecting member connected to and projecting from a body of the workpiece and movable along a first axis and a second axis,
wherein movement of the adjustment device along the first axis when engaged to the projecting member adjusts the projecting member along the first axis relative to the body, and wherein movement of the adjustment device along the second axis when engaged to the projecting member adjusts the projecting member along the second axis relative to the body.

11. The fixture of claim 10 , wherein the adjustment device comprises a movable member and an engageable member.

12. The fixture of claim 10 , wherein the adjustment device is pivotable between a first position wherein the adjustment device is movable along the first axis and a second position wherein the adjustment device is movable along the second axis.

13. The fixture of claim 10 , further comprising a locating device configured to assess a location of the projecting member.

14. The fixture of claim 10 , wherein the holding device is a clamp.

15. The fixture of claim 10 , wherein the holding device is engageable to an end portion of the workpiece.

16. The fixture of claim 10 , wherein the first axis is an x-axis and the second axis is a z-axis.

17. The fixture of claim 10 , wherein the workpiece is a transition piece and the projecting member is a mounting bracket of the transition piece.

18. A method for adjusting a workpiece, the method comprising:
securing the workpiece such that the workpiece is generally fixed;
engaging a projecting member of the workpiece with an adjustment device, the projecting member connected to and projecting from a body of the workpiece;
moving the adjustment device relative to the body at least one of a first axis or a second axis to adjust the projecting member relative to the body along the at least one of the first axis or the second axis.

19. The method of claim 18 , further comprising assessing a location of the projecting member.

20. The method of claim 18 , further comprising pivoting the adjustment device between a first position wherein the adjustment device is movable along the first axis and a second position wherein the adjustment device is movable along the second axis.
